VALVE.

To all whom it m (13 concern Be it known that'l, F RANKLIN M. PATTER-soN, a citizen of the United States, and a resident of the city andcounty of Philadelphia, State of Pennsylvania, have invented anImprovement in Valves, of which the following is a specification.

My invention has reference to valves and consists of certainimprovements which are fully set forth in the following specificationand shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a construction of reversiblethrouglnvay valve which shall be positive in action, durable in use,inexpensive in construction and easy of repair.

My invention consists of a valve casing made in three parts, namely: amiddle annular body part of uniform thickness and two outer parts boltedto the middle part with interposed packing, said outer parts being eachprovided with a port which ports come into alinement when the casing isassembled, combined with a pivoted spindle and a swinging valve pieceadjust-ably carried by the spindle whereby it may follow the valve seatupon one of the outer parts.

My invention further consists in providing the two outer parts of thevalve casing with valve seats about their ports and extending laterallytherefrom to..form opposing parallel surfaces with the valve piece,adapted to swing between the said valve seats, of less thickness thanthe space between the said seats and adjustably connected on thespindle, whereby said valve piece may automatically adjust itself on thespindle and to either seat according to which of the two ports is usedas the outlet port.

My invention further consists of a valve of the character abovedescribed, in which the spindle for operating the valve piece has acylindrical bearing in each of the outer parts, and a flanged portionseating in a bearing in one of the parts, combined with a springarranged in the other of the parts for forcing thespindlelongitudinally, whereby its flange may positlvely seat itself onthe bearing.

My invention also comprehends details of construction which, togetherwith the features above specified, will be better under- Specificationof Letters Patent.

stood by reference to the drawings, in which:

Figure 1, is a plan view of my improved valve with the middle and one ofthe outer portions of the case removed. Fig. 2 is a transverse sectionalelevation on a plane through the center of the ports and spindle; and,Fig. 3 is a perspective view of the spindle removed.

A is the middle portion of the case and is annular in form and somewhatsegmental in plan, as indicated in Fig. 1. It is clamped between twoouter parts or heads B and C of the case, by means of bolts 1), asindicated. The outer parts, B and C of the case are provided with portsE having screw threaded portions 1 for attachment to the piping. Insteadof these screw threaded portions, the ports maybe made in any othersuitable manner for connection with piping or devices with which thevalve is to be employed, as will be understood by those skilled in theart. In large valves it is customary to provide flanges insteadof-relying upon the screw threads of the pipe for direct attachment."The opposing faces of the parts A, B and C are made flat and providedwith small grooves c in which packing strips H are arranged, so thatwhen the bolts 1) are tightened up the joints between the parts A, B andC are made water tight without requiring the opposing surfaces to beplaned or turned. By this construction, economy is secured with respectto the cost of manufacture. Furthermore, all of the bolts with theexception of three, which are indicated in cross section in Fig. 1, mayloosely fit the holes in parts A, B and C, but these three bolts aremade to fit snugly to enable the spindle bearing to be bored in the twoparts B and C in exact alinement. In place of the tight fitting bolts,being those indicated in cross section, in Fig. 1, any other of thebolts might be so made, as long as the parts B and C are held in properrelation to insure the alinement of the bearings for the spindle F.

Each of the outer parts, B and C is provided with a valve seat Gsurrounding the ports E, and these seats extend laterally as indicatedin Fig. 1. These seat portions Ur extend beyond the level of the flangeportions, which are clamped to the middle part arranged a spring M whichis carried upon the rocking spindler' j ournaled at J in the outer partC. The

spindle is of the shape shown in Fig. 3,'

and consists of the part F which is cylindrical and journaled at J inthe part C as aforesaid; the flange F which is cylindrical and fittedinto a circular recess in the part 7 and resting upon an annular packingring K between the said flange and the bottom of the recess to make atight joint, and which packing ring K may be of copper or othernon-oxidizable metal; the part F which is made with straight sides andpreferably curved at each end and extends upwardly from the flange partof the spindle, and snugly fits an aperture 1 in the swinging valve 1;and a cylindrical part F having an axis in line with the axis of thecylindrical part I and journaled in a recess L in the other outer partB. Within the recess is which presses upon the end of the part F of thespindle to force said spindle longitudinally so that the flange 1thereof will make a tight joint with the packing K on the other outerpart 0.

The swinging valvepiece I is shown in Fig. 2 operating against the-valveseat in the outer part C, and does not quite touch the valve seat on theouter part B. Under these conditions the port in the part C would be theeduction port or outlet, as the pressure of the water entering the valveforces the valve piece against the seat of said outlet port. Should thevalve be reversed, it is evident then that the port in the other outerpart B will become the eduction or outlet port, and in such case, thepressure of the water will force the valve piece I against the valveseat of the part B, and cause it to leave the valve seat which it is nowoccupying. This capacity of the valve necessitates a freedom of movementbetween the valve and spindle as the spindle is not intended to havelongitudinal movement excepting to permit adjustment to compensate forWear. I

The spindle F may be rocked by any suitable means, but in the formpreferred, I employ a segmental gear N, fitted upon the square end ofthe spindle and driven by means of a pinion N upon theend of the lever Nwhich is pivoted upon a stud 0 carried by an extension of the outer partC of the case. If the lever N is rotated in the reverse direction to thehands of a clock, the valve piece I will be moved to expose the outletport, and reversely to close it, the hand lever making preferably abouta half revolution to obtain a full opening of the valve.

By the construction herein described, it is evident that very littlemachine work is required upon this valve, and such as is requiredinexpensive. The valve, as a whole, is easily dismantled and repaired,and from the nature of its construction, the cost of manufacture isreduced to a minimum.

By making the spindle with the block F mainly at one side of the axialline, I am enabled to make the slot in the valve piece largely betweenthe axis of the spindle and the valve proper, and in this way, permitthe valve to encircle the spindle without abnormally increasing the sizeof the case constituting the valve body.

While I have shown my invention in the form which I have found mostexcellently adapted for commercial use, I do not limit myself to thedetails,as these may be modi-' fied without departing from the spirit 01the invention. 1

Having now described my invention what I claim as new and desire tosecure by Letters Patent, is-

1. In a valve, a casing having ports in alinement and provided on oneside with a long cylindrical bearing having a cylindrical recess at itsinner end, said recess providing at its bottom an annular flat bearingsurface at right angles to the axis of the bearing, in combination witha spindle journaled in said bearing so as to have wearing contact up tothe recess and having a cylindrical collar fitting said recess andprovid-' ing an annular flat Wearing surface fitting the annular fiatbearing surface of the recess, said spindle also having an irregularshaped block portion on its inner end beyond the collar, a springbetween the inner end of the spindle and the opposite side of the casingacting to hold the spindle in position and its collar in the recess ofthe bearing, and a swinging valve structure independent of the spring,having a' socket fitting over the irregular shaped block portion of thespindle and positively movable therewith to swing transversely betweenthe ports of the casing to control flow through said ports, said valvestructure also movable longitudinally upon the spindle.
